CSP4 & DSP4 2017-18 release

2 November 2018

EFILive is pleased to announce the public release of CSP4 and Enhanced Data Acquisition (EDA) for 2017 and 2018 6.7L Cummins Pickups, and DSP4 for 2018 2.8L vehicles using the E98 GM Diesel controller.

CSP4 and DSP4 allows customers to switch 'on the fly' between a number of different tunes, all stored in the ECM's flash memory. By having multiple tunes instantly accessible, customers no longer need to re-flash their ECM to change their tunes to suit changing conditions (e.g. racing, towing or power limiting). Simply build up your tunes, flash the ECM once and then select your desired tune through your EFILive hardware (or other approved switching devices) at any time. Approved Cummins switching options are listed here, and approved Duramax switching options are listed here.

For Cummins vehicles, upgrading to CSP4 also provides access to EDA, a single group of hand selected parameters deemed as essential for tuning feedback.

This CSP4 and DSP4 release is a FREE software update to all EFILive customers. To access these features, customers must update their V8 and V7 software, along with their FlashScan V2/AutoCal firmware to our October 2018 public release software.
